Iraq as part of OIF III (Operation Iraqi Freedom III, the third U.S. military rotation of forces into the area of operations). It served under the 1st Cavalry Division for its first five months and its last several months under the 3rd Infantry Division. During the first half of its combat tour in Iraq some of the brigade's subordinate units also served under the 10th Mountain Division. The brigade served in and around Baghdad, Iraq in a FOB known originally as FOB Victory until 15 June 2004. At this date FOB Victory's name was changed to FOB Liberty because on this date the Iraqi government officially "stood up". Upon the 256th's arrival at North Liberty it became Camp Tigerland. During operations in theater the brigade operated under the configuration of one-third heavy and two-thirds light. Each battalion in the brigade had one company of heavy forces with M1A1 Abrams main battle tanks, M2A2 Bradley infantry fighting vehicles, or a mixture of the two. The other two-thirds operated primarily from HMMWV Gun Trucks that mounted either machine guns or automatic grenade launchers. The field artillery battalion was cannibalized to bring the infantry battalions up to full strength. The remainder of the Washington Artillery was attached to the 1st Cavalry Division base defense operations center (BDOC) under the command of the 103rd Field Artillery Brigade and the XVIII Airborne Corps. One howitzer platoon from the Washington Artillery was used to provide indirect fires in support of FOB Liberty. Additionally, Task Force Bengal was "stood up" as a liaison/training team to equip, train and assist the 40th Iraqi National Guard (ING) Brigade. TF Bengal consisted of soldiers and officers of the infantry, field artillery, and engineer units from the 256th Brigade as well as the 1st Battalion, 69th Infantry (The Fighting 69th) from New York City which had been attached for the deployment. Attached to the 69th Infantry was Delta 101, a company of tankers and scouts turned infantrymen from New York's 101st Cavalry Regiment. During the American Civil War, the 69th engaged the ancestral units of the 256th many times, so their attachment to each other for OIF provided a symbolic reconciliation 140 years after they fought each other to the death repeatedly from 1861 to 1865. On 21 February 2005, the 40th ING Brigade assumed authority for approximately 16 square kilometers in and around Al Akadhimian and began patrolling with approximately
